Consider this scenario. In Microsoft Office SharePoint
Server 2007, you perform a profile import when domain controllers in a domain
are unavailable. The profiles for that domain are marked as "Profiles missing
from import". However, each of these profiles belongs to an account.

In this scenario, the MySiteCleanup job does not resolve these
accounts from that domain. Additionally, these accounts are deleted together
with their MySite sites.
